Preacher Witting is a minor character in BioShock Infinite. Witting is first seen in the Welcome Center, offering Booker DeWitt baptism and thereby passage into the city of Columbia.

As Booker enters the circle of devotees at the exit of the Welcome Center, Preacher Witting appears to be blind, asking, "Is it someone new?", a reference to the first Spider Splicer from the original BioShock, as seen here.

As minor of a character as he may seem throughout most of the game, keen observers will notice that Preacher Witting is also the same preacher present at Booker DeWitt's optional baptism at the very end of the game.

This appearance would lead one to believe that, in the alternate dimension wherein Booker accepted the baptism and was reborn as Father Comstock, Comstock took Witting in as a close confidant and recruited the preacher to help found his new "religion".

As for when Witting's blindness occurred, one can only speculate. However, being blind was oddly convenient for Booker as Witting would have surely recognized DeWitt in the Welcome Center. Perhaps Booker blinded the man in one of his previous attempts to enter Columbia to give himself a stealthy entrance into the city.
